I've been on Tri-Previfem birth control pills for almost two years, and I've never had a problem. We had insurance issues, so I switched the pharmacy at which I get my prescriptions filled. I got Tri-Sprintec instead of Tri-Previfem, which are different generic brands of the same name brand product. They are the exact same hormone levels and distribution.
However, both this month and last month, the first two that I've been using Tri-Sprintec, I've gotten my period on about day 12, which is a week and a half early. And it's a full flow period and it lasts until I start week 1 of the next pack of pills. It's rather inconvenient.
I was wondering if this has happened to anyone else, and if I should contact my doctor now or wait it out another month to see if my body needs to get used to the slightly different prescription.
PS I know you're likely not doctors. And I'm in college, far from home, so it makes the visit a little cumbersome.

Some women do experience a change in side effects when switching from brand name to generic, or from one generic to another. In general, when starting the pill or switching brands, you do want to give yourself about three months for your body to adjust, but there's no harm in phoning your doctor to see what they recommend.
Alternatively, is there a health center on your campus? That's another option if you want to discuss this with a doctor in person.
